Casaubon – and Cicero?

At Laudator Temporis Acti, Michael Gilleland quotes a witticism of Casaubon. It looks to me like a far more succinct variation on a story Cicero tells in his De Legibus – or rather has his character Atticus tell, since it’s a dialogue. I posted the story as the second item on my Ancient Jokes page eleven years ago. (I hope to restart the page at some point, but as a searchable database.) I wonder whether the learned Casaubon was alluding to Cicero, and if so, whether he expected his hearers to recognize the allusion.
